Development and Preliminary Validation of the 6-Item Short Form of the Wisconsin Stone Quality of Life Questionnaire.

Objective: To develop a short form of the Wisconsin Stone Quality of Life (WISQOL): 1) identify the smallest subset of items from WSIQOL that accurately predict patients' health-related quality of life (HRQOL), and 2) in a clinical patient population, test these items-grouped together to form the WISQOL-short form (SF) - and assess its convergent validity.

Materials And Methods: The items for the WISQOL-SF were identified based on classic item analysis theory. Patients who previously completed the original 28-item WISQOL were randomly split into 2 groups of equal size.

Pulse-modulated Holmium:YAG Laser vs the Thulium Fiber Laser for Renal and Ureteral Stones: A Single-center Prospective Randomized Clinical Trial.

Purpose: We sought to compare the clinical effectiveness of the pulse-modulated Ho:YAG (holmium:yttrium-aluminum-garnet) laser and the thulium laser fiber for ureteroscopic stone management in a randomized clinical trial. The primary outcome was the ureteroscope time required to adequately fragment stones to 1 mm or less. Secondary outcomes were stone-free rate, complications, subjective surgeon measurement of laser performance, patient related stone quality of life outcomes, and measurements of laser efficiency.

Ureteroscopy and Shock Wave Lithotripsy Trends from 2012 to 2019 Within the US Medicare Dataset: Sharp Growth in Ureteroscopy Utilization.

Both ureteroscopy (URS) and shock wave lithotripsy (SWL) are cornerstones in the surgical management of urolithiasis in the United States. We hypothesized that URS utilization outpaced SWL utilization in recent years and quantified the magnitude of change over time for caseloads of URS and SWL among urologists from a national Medicare database. Using the public "Medicare Physician & Other Practitioners" database (https://data.

A Novel Risk Prediction Model to Triage Difficult Urethral Catheterizations.

Objective: To construct a risk prediction model to identify cases of difficult urethral catheterizations (DUC) in order to prevent complications from improper placement.

Materials And Methods: Using a single-institution database of urologic consults for Foley catheterizations from June 2016 to January 2020, a model to predict DUC in male patients was constructed. DUC was defined as requiring the use of a guidewire, cystoscopy, urethral dilation, and/or suprapubic tube (SPT) placement, while a simple Foley was defined as an uncomplicated placement of a regular or coudé catheter.

A population-based analysis of risk factors and outcomes of prostatic abscess.

Background: Prostate abscess is a severe complication of acute bacterial prostatitis. To date, a population-based analysis of risk factors and outcomes of prostatic abscess has not been performed.

Methods: Using the National Inpatient Sample from 2010 to 2015, we identified rates of prostatic abscess among non-elective hospitalizations for acute prostatitis.

Survival and oncologic outcomes of complete transurethral resection of bladder tumor prior to neoadjuvant chemotherapy for muscle-invasive bladder cancer.

Objectives: Prior studies have shown that pathologic complete response at radical cystectomy, a significant prognostic factor, can be attributed to both neoadjuvant chemotherapy (NAC) and high-quality transurethral resections (TURBT) prior to NAC. It remains unclear whether the visual completeness of TURBT prior to NAC plays an important role in subsequent outcomes. We sought to assess the association of completeness of TURBT prior to NAC with response and survival outcomes.

Delayed Decompression of Obstructing Stones with Urinary Tract Infection is Associated with Increased Odds of Death.

Purpose: Obstructive pyelonephritis is considered a urological emergency but there is limited evidence regarding the importance of prompt decompression. We sought to investigate whether delay in decompression is an independent predictor of in-hospital mortality. Secondarily, we aimed to determine the impact of patient, hospital and disease factors on the likelihood of receipt of delayed vs prompt decompression.

Temporal Trends and Practice Patterns for Inpatient Management of Malignant Extrinsic Ureteral Obstruction in the United States.

Malignant extrinsic ureteral obstruction (MEUO) is a challenging clinical problem. Many factors weigh into the decision to proceed with retrograde ureteral stent (RUS), nephrostomy tube (NT), or observation; however, there is no consensus for the optimal approach. The objective of this study was twofold.

Salvage Therapy Using Bacillus Calmette-Guérin Derivatives or Single Agent Chemotherapy.

Despite therapy with intravesical Bacillus Calmette-Guérin, roughly 50% of patients with high-risk non-muscle-invasive bladder cancer will recur. Although cystectomy is the oncologic gold standard in BCG unresponsive disease, salvage intravesical therapies are valuable treatment options that aim to preserve quality of life while decreasing the risk of cancer recurrence and progression. Single-agent intravesical chemotherapy has been a mainstay salvage treatment and foundational to future trials of combination therapy.

The Timing of Radical Cystectomy for bacillus Calmette-Guérin Failure: Comparison of Outcomes and Risk Factors for Prognosis.

Purpose: We compared the pathological and survival outcomes of patients who underwent radical cystectomy soon after bacillus Calmette-Guérin failure with those of patients who received additional salvage intravesical chemotherapy before cystectomy for nonmuscle invasive bladder cancer. We also identified predictors of prognosis in the entire cohort.

Materials And Methods: We retrospectively analyzed the records of 117 patients who underwent radical cystectomy for recurrent nonmuscle invasive bladder cancer at our institution from 1990 to 2012.
